I joined in 2011 and I've made, like, 1 build I'm actually decently proud of. I've made a lot of builds, but they where pretty crappy. I even made a space-jail rp, that was decently popular(and one of the heights of my bl playing experience) but I guarantee nobody remembers it but me. I've always considered myself a futuristic-build builder; yet have made just 1 spaceship(that was actually incredibly good for a first try, but just okay for a space-ship). For a long time my houses where very simple, a x1 black brick, x5 white, x1 black and curved bricks on the corner.
My advice, though, is to go to other people's freebuilds and start building. It's loads of fun there, and I know almost nobody freebuilds at a freebuild, but trust me it's fun--those people don't know what they're missing out on.
